To to whom it m/u/gi concern.-

Be it known that I, JOSE GALLEGOS, a citizen of the Republic of Guatemala, and a resident of San Jos de Guatemala, in the Republic of Guatemala, have invented new and useful Improvements in Static Electric Machines, of which the following is afull, clear, and exact description.

My invention relates to static electric niachines of the class known as influence or induction machines, and has for its object to provide a very elhcient machine of the above-indicated class.

To this end my invention consists of certain novel features of construction and combinations of parts, as will be fully described hereinafter and specifically pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the improved machine. Fig. 2 is an end elevation thereof, with parts in section, on the line 2 2 in Fig. 1. Fig. 3 is a view similar to Fig. 1,

but with the parts in a different position andshowing those electrical connections which for the sake of clearness are omitted from Fig. l; and Fig. 4 shows a simplified form of construction.

Upon the base A is fixed a stationary ring A, preferably made of wood and having inward radial projections A (likewise of wood,) upon which are wound coils of insulated wire a, one end of each coil being connected with a metal plate I) at the inner end of the pro jection, while the outer ends of the coils are connected alternately by wires 0 and 0, respectively, with binding-posts C C. These posts are adapted for connection by wires d d with a source of static elect-ricityf or instance, as shown, the collectors D D of a friction electric machine. The stationary parts so far described constitute what may be termed the exciting elements of the machine.

The excited or delivering part of the machine comprises the following movable elements: A wheel E is journaled by trunnions B in bearings A of the base A and carries a pulley E, by which power may be applied I to turn the wheel, generating-coils F, and a collector G. The coils F are constructed similarly to the coils a and correspond to them in number and position. The outer ends of the coils F are connected with meta-l plates (2, adapted to pass close to the metal plates Z), the two sets of plates being insulated from each other simply by the intervening air or by a cylindrical sheet f, of insulating material, such as glass, carried by the wheel 13 or by the stationary base, preferably the latter. The inner ends of the coils F are connected with contact-plates g on the collector G. These contact-plates are adapted to be engaged by stationary collectingbrushes H, the number of which is double that of the contact-plates, some of the brushes being arranged to engage the contact-plates when the coils e and F register, as shown in Fig. 1, while the other brushes engage the contactplates when they are in the inter mediate position. (Shown by dotted lines in Fig. l and better represented in Fig. 3.) Of those brushes which engage the contactplates in the position shown in the drawings alternate ones are connected by wires 0 and 0, respectively, with binding-posts C 0; connected to the ground by wires (1 (1. Of the intermediate collecting-brushes alternate ones are connected by wires 0 and c respec tively, with the binding-posts C' and C, from which connection is made to any a1)paratus (for instance, a spark-discharger l)-in which the electricity produced is to be utilized.

The machine is operated simply by rotating the wheel I after giving the coils a an initial charge of electricity by connecting the binding-posts (J G with a source of static electricity, as shown. The coils F being conected to the ground when they stand opposite the coils a will by in fluence receive a charge of opposite polarity, as indicated in Fig. 1, and when the coils F get into the intermediate position (shown in dotted lines) they will be in connection with the binding-posts C C and will discharge their electricity into the consumption apparatus 1. It will be seen that the machine produces both positive and neg ative electricity and that by reversing the wheel B the binding-posts 0 0 may be caused to receive the charge of either positive or neg ative electricity. The parts a and F are formed into coils to secure considerable ca.- pacity with a relatively small bulk.

It will be obvious that the machine is a double one and receives and yields both posi tive and negativeelectricity. Further, it will be evident that the machine consists virtually of two independent halves and that by leaving one-half out of action the machine may be operated to receive positive electricity only and deliver only negative electricity, or vice versa. Of course I might, as shown in Fig. 4, construct a machine embodying only one of the halves-that is, having a series of stationary coils ct",all connected by a wire 0 with the same binding-post C, a series of movable coils F, all connected to the ground through their contact-plates g, brushes H, wire c and binding-post 0 when they stand opposite the stationary coils, and other brushes H wire 0 and binding-post C for taking the charge off the coils F when they stand in their intermediate position. It will be seen that in each construction the number of collecting-brushes is double that of the stationary coils. It would be an obvious equivalent to have the brushes revolve and make the contact-plates stationary. Of course the machine is reversible and may be used as a motor, if desired. Further, it will be understood that a connection to the opposite pole of the exciting-machine is the equivalent of a ground connection.

W'ires d (1 may also be connected with a source ofdynamic electricity, like voltaic one, with which electrieity-condensers may be charged. The coils,if desired, may be omitted, leaving only the metal plates to form the condensers. The coils may have an iron core for obtaining a stronger induction-enrrent.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A static-induction machine, comprising a series of stationary coils and means for connecting them with a supply of static electricity, movable coils arranged to pass adjacent to the stationary coils, and collecting devices for connecting the movable coils with the ground when they register with the stationary coils, and for connecting the movable coils with a consumption apparatus when they are in a position between the stationary coils.

2. A static-induction machine, comprising a series of stationary coils and means for connecting them with a supply of static electricity, a wheel carrying a series of movable coils arranged to pass adjacent to the stationary coils, and collecting devices, the number E of which is double that of the stationary coils, one half of said collecting devices being constructed to connect the movable coils with the ground when they register with the stationary coils, and the other collecting devices being arranged to connect the movable coils with a consumption apparatus when they are in an intermediate position.
